It will take a while to clean, any ideas? It might just be nothing but when I took some of the clay away a familiar shape emerged.
Found in clay conglomerate, Rd Cut exposure of barely transited state back road. Clay conglomerate is basal to red clay and silt stone followed by dark grey shales (organic) suden change to sandatone divides this formation from the Sanford Sub-Basin.June 6, 2016 at 10:59 pm #5825
More photos, sorry for the low quality.June 12, 2016 at 9:14 pm #5855
Still no ID, found multiple teeth of different shapes all in line but inbeded deep in matrix.June 17, 2016 at 6:15 pm #6065Eleanor GardnerModerator
Hmm, this is interesting @alex-rosas! I’m not sure what you have there. You might have to continue working on the clean-up and send in updated pictures every once in a while. Sean Moran @smoran has been working on IDing a bunch of teeth this past week — any ideas, Sean?
Keep up the good work, Alex!

Hi Alex, @alex-rosas, from the pictures these teeth like structures look like crystallization to me. I see several crystals in different size and shape, something not unusual in concretions like this. If you think that these are fossil teeth we will have to have a closer look under the scope, better images or a single tooth to prove it. Sorry I wish I could tell you something more specific.
all the best

Will get it under the dissection scope tomorrow evening. I also will like to send you a photo of the other side of the concretion tonight as it is the cleaner section @rleder.
Will get back to you.
Best regards guys and thank you!

Photo 1. This is the side of the concretion I have been working on. Opposite to the crystals. I am out of my home and took it with me on a trip, so pictures are not the best.June 18, 2016 at 4:38 pm #6076June 18, 2016 at 4:39 pm #6078June 18, 2016 at 4:41 pm #6080June 20, 2016 at 12:24 pm #6250
Hey Alex, @alex-rosas, thank you so much for the pictures. Now I am quite sure that this is a nice example of a gap filling. The gap space was perfect for crystallization of quartz out of a silicate rich fluid. The crystals have enough space to grow and they grow all from the same origin (the edge of the gap) into the free space. That is my interpretation. Any thoughts from my colleagues @smoran, @vperez, @egardner ?

… ahh and the crystals are hexagonal … characteristic for quartz!June 20, 2016 at 12:29 pm #6254
Awsome @rleder! Appreciate it dearly! Will find a use for it and move on!June 20, 2016 at 12:33 pm #6255
